| 20090196917 | Liposomal Formulations of Hydrophobic Lactone Drugs in the Presence of Metal Ions - Disclosed herein is a liposomal formulation that comprises a liposome and a liquid carrier. In the liposomal formulation, the liposome comprises a hydrophobic lactone drug and has an intraliposomal metal ion concentration higher than the metal ion concentration of the liquid carrier. Also disclosed herein is a method for active loading of a hydrophobic lactone drug into a liposome. The method includes preparing a liposome in the presence of a metal salt solution, an acid form of a counterion of the metal salt being membrane permeable, such that the liposome preparation contains entrapped metal ion. The method further includes forming a liposome with high intraliposomal pH by separating extravesicular metal salt solution from the liposome by exposing the liposome to a metal salt-free solution, resulting in diffusion of the acid form of the counterion out of the liposome and formation of an intraliposomal pH higher than that of the metal salt-free solution. The method also includes exposing the liposome with high intraliposomal pH to an isoosmolal solution containing a hydrophobic lactone drug, the isoosmolal solution having a pH lower than the intraliposomal pH, such that the hydrophobic lactone drug accumulates in the liposome predominantly in its ring-opened form. | 08-06-2009 |
